COMBINED EXHAUST AND GEAR CASING.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed June 13, 1919. Serial No. 304,075.

To [ZZZ 20/ 10111 it may concern Be it known that I, FRANK E. GOSSETT, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois. have invented certain new and useful Improvements in a Combined EX- haust and Gear Casing, of which the following is a description, reference being had to the accompanying drawing, which forms a part of my specification.

My invention relates more particularly to a combined exhaust and gear casing for use on tractors and the like whereby the bull gear is provided with a housing or casing to protect it from dirt and weather; while at the same time the casing is arranged to receive the exhaust gases from the motor of the tractor in such manner that the oil suspended in the gases is employed for lubricating the toothed surfaces of the gear and driving pinion, thereby providing a more eificient operating tractor, wherein the gearing or driving members for the drive or traction wheels will be made smoother running and maintained free fron'i grit or dirt, with the result that the efficiency and life of the gearing is greatly enhanced.

The objects and advantages of my improved construction will be more readily comprehended from the detailed descrip tion of the drawing, wherein Figure 1 is a partial plan and sectional view of the wheel-type of tractor provided with my improvement; with the motorand transmission mechanism illustrated in a more or less diagrammatic manner.

Fig. 2 is a detail sectional view of the casing portion of my invention and a side elevation of a portion of one of the tractor wheels and gearing.

In the particular exemplification. the tractor is shown provided with a suitable frame 10 to which is secured, in any well known manner, a suitable internal combustion motor shown at 11, which in the particular exempliflcation is illustrated as of a four cylinder type and provided with an exhaust manifold 12 to receive the exhaust gases from the respective cylinders. The exhaust manifold communicates with a transversely disposed conduit 13, shown in section in Fig. 1. The conduit 13 is disposed from side to side of the tractor frame and has its ends secured in suitable openings formed in the stationarily secured casing members 14, 14 of the driving gear casing. The members 14, 14 in the particular exemplification, comprise annularplates which are shown provided with bosses, see Fig. 1, disposed about the apertures so as to enable the ends of 'the'transversely disposed conduit 13 to be properly secured in place. The ends of conduit 13 preferably enter the stationarily secured members 14 of the casings, at a point in close proximity to the meshing or operative contact point of the driving pinion 15 with the'bull gear 16,.seeFig. 2, .so that the exhaust gases are caused to be discharged onto the toothed surfaces of the two gears. With the exhaust gases discharging at such points, it is evident that any grit or dirt that may have lodged on the operat ing surfaces of thegears will not only be dislodged, but said surfaces will also be provided or covered with the oil or hydrocarbon contained in and discharging with the exhaust gases and the operating or toothed surfaces of the pinions 15 and bullgears 16 thereby lubricated.

The members 14 of both casings are suitably secured, by bolting or otherwise, to the frame of the tractor against rotation or movement; While the opposite side wall or member 17 of each casing is suitably secured to the driving or tractor wheels 18, 18, or to the bull-gears 16, 16, so as to rotate therewith. The stationarily secured members 14. 14 of the two casings are each preferably provided with a peripheral flange 19 disposed toward the opposite side wall or member 17 of each casing; it being understood, of course, that the stationarily secured members 14 are of sufficient diameter so that the peripheral flanges 19 will encircle the bullgears and driving pinions and in the particular exemplification. the side wall 1nem bers 14 are shown smaller in diameter than members 17 a condition which may be reversed if desired. The members 17 of both casings are likewise provided with peripheral flanges 20 disposed in the opposite direction to the peripheral flanges 19 of members 14; the members 17 with their peripheral flanges 20 being of greater diameter than the members 14, in order that the peripheral flanges 20 of members 17 may encircle the flanges 19 of the stationary members 14, see Fig. 1. The members 17 with their peripheral flanges 20 are preferably of such diameter as to leave a small intervening space between flanges 19 of members 14 and flanges 20 of members 17, so as to-not only avoid frictional contact between the flanges, but also provide sufficient space for the escape of the exhaust gases from the casing. With the construction and arrangement of the parts as shown and described, the exhaust gases will be discharged toward the operating surfaces of the pinlons 15 and bull-gears l6, and thus induced to contact with the pinions and gears before the gases are permitted to further expand in the casing and permitted to escape through the circumferential passage formed between the two members or walls of the gear-casing.

It is evident that the rotating walls or members 17 of the casings may be secured in any suitable manner to the bull-gears or to the traction wheels so as to rotate therewith, namely by either securing them to the spokes of the wheels or to the hubs in any well known manner; and, furthermore, it is apparent that the invention as shown in the drawing and described in the specification is susceptible of modifications capable of performing the functions herein described and of obtaining the advantages of my invention without, however, departing from the spirit'of the invention.

What I claim is I. In a device of the class described, the combination with the exhaust manifold of an internal combustion motor, of a conduit communicating with said manifold and dis posed transversely, said conduit being adapted to discharge the exhaust gases at both ends thereof, a bull-gear casing comprising an annular disk or plate stationarily secured to the ends of said transversely disposed conduit and of diameter suflicient to encircle the driving pinion and bull-gear, and a second annular plate adapted to rotate with the bull-gear and of diameter sufficient to encircle the driving pinion and bulb gear, the peripheries of said annular plates being formed to inclose the space intermedi' ate of said plates and at the same time pro vide escape of the exhaust gases.

2. In a device of the class described, the combination with the exhaust manifold of an internal combustion motor, the driving pinion and bullgear of a tractor, of a con duit disposed transversely intermediate of the driving wheels of the tractor and arranged in communication with the exhaust manifold of the motor, an annular plate socured about each end of said conduit and apertured to permit discharge from the orifices of said conduit, said annular plates being secured against rotation,and a second set of annular plates adapted to rotate with the bull-gears or drive wheels of the tractor,

scopic relation and adapted to encircle the bull-gears and driving pinions of a tractor, one side wall member of each casing being stationarily secured and apertured at a point in proximity to the contacting surfaces of the pinions and bull-gears while the other member of each casing is adapted to rotate with the bull-gears, and a conduit, communiating with the exhaust manifold of an internal combustion motor, arranged transversely of the tractor with its ends secured in the apertures of the stationarily secured sid wall members.

In a combined exhaust and gear casing of the class described, a side wall member secured to the frame of the tractor against rotation and on one side of the bull-gears and drivii'ig pinions thereof, a second side wall member secured to rotate with the bullgears and on the opposite sides thereof, both side wall 'HIBIDbGTS being provided with oppositely disposed peripheral flanges arranged in telescopic relation so as to encircle the gearing, and an exhaust-gas-receiving conduit arranged in communication with the exhaust manifold of the motor, said conduit having its ends disposed through the first mentioned. side wall member of each casing and adapted to discharge the exhaust gases at a point in proximity to the contacting surfaces of the driving pinions and bullgears.

5. In a device of the class described, the combination with the exhaust'manifold of an internal combustion motor, of a conduit communicating with said manifold and dis posed transversely and arranged to dis char the exhaust gases at both ends there of, and a bull gear casing comprising a plate stationarily secured to each end of said transversely disposed conduit and a second plate disposed on the opposite side of and adapted to rotate with each bull gear, both sets of plates being formed to inclose thebull gears and pinions and permit the exhaust gases to escape therefrom.
